GTx, Inc announced that in the phase-III clinical trial evaluating toremifene 80 mg for the reduction of fractures and treatment of other estrogen deficiency side effects in men with prostate cancer on androgen deprivation therapy (ADT), toremifene treatment demonstrated an improved benefit/risk ratio in men less than 80 years of age. The data were presented yesterday at the 2010 Annual Meeting of the American Society of Clinical Oncology in Chicago.

"Data from the TREAT 1 clinical trial clearly show that toremifene treatment had a more pronounced fracture reduction and better safety profile in men less than age 80," said Mitchell S Steiner of GTx. "Based on these results, we designed the TREAT 2 phase-III clinical trial which will enrol men with prostate cancer on ADT with measured bone loss who are younger than 80 years. We expect this next study to confirm the robust fracture reduction which toremifene 80 mg demonstrated in the first Phase III clinical trial, the TREAT 1 study."
